The first known semi-natural appearance of this oscillator was in December 2014, in a symmetric soup found by Dongook Lee using apgsearch.[2]

A 46-glider synthesis of this oscillator was found by Jeremy Tan on January 5, 2020.[3]

gollark: It might also™ be possible to have it cache *all* the site on every website update, but that would be a bit wasteful.
gollark: This™ does have the minor disadvantage that™ you'll need to refresh the page™ to receive site updates™ sometimes™, so that™ it loads the service worker™ again to detect™ the new™ version.
gollark: If you visit a page, it will now use magic™ to cache it locally, and then serve that local copy until it detects that the site has been updated, and that will continue to work even without an Internet connection with cached pages.
gollark: Good news! I fixed the service worker setup, so you can now use osmarks.tk offline (ish).
gollark: I should offer some sort of API for RAM downloads.
